I wish these intakes could become somewhat more reasonable on price.

If only we could more easily open up the stock intakes and have a way to reliably seal them back up and we could grind down the runner lengths and do more internal porting. Seems like it you could open up a GEN IV truck intake you could grind down the runners to get the shorter length you need for high rpm operation.

 

Wasn't there a guy on here not too long ago who used a backyard foundry to make his own intake? Or was that an exhaust manifold?

 

PeakSpeed opens them up with their porting service. For the TBSS they charge $450 and the gains are 13rwhp & 20rwtq. If you don't already have the complete TBSS setup... the Fast may be a better option.

Holy **** that is a difference!

 

Did Peak Speed Shop go out of business? The web address doesn't work, if they did does anyone know of a place that ports the plastic intakes anymore?

I seem to recall there were a couple guys on facebook or instagram that were porting these, some being local to you.

I can’t remember for the life of me though the names. Maybe check LS1Tech as well
